Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.32.5, `kiota info` read x-ms-kiota-info.languagesInformation.<language>.dependencyInstallCommand plus dependency name and version values from an OpenAPI description and presented the spec-supplied command as Kiota's recommended install command, allowing an attacker-controlled or compromised description to cause command injection when the suggested command was run manually or through the Kiota VS Code extension's kiota info --json dependency-install flow. This issue is fixed in version 1.29.1 and 1.32.5.
